Disclosure Statement of Financial Interest
I, Demetrio R. Macariola , DO NOT have a financial
interest/arrangement or affiliation with one or more organizations that
could be perceived as a real or apparent conflict of interest in the
context of the subject of this presentation
Disclosure Statement of Unapproved/Investigative Use
I, Demetrio Macariola, DO/DO NOT anticipate discussing the
unapproved/investigative use of a commercial product/device during
this activity or presentation.
1. Describe the different immune deficiency syndromes in our community in outpatient
setting.2. Describe the pathogens associated with
each deficiency syndrome.
Learning Objectives
Immune Deficiency Syndromes in the Appalachia over 4 years
CVID: 20Agammaglobulinemia: 2Transient Hypogammaglobulinemia: 2Chronic Granulomatous Disease: 4Hyper IgE Syndrome: 2HIV: 1TOTAL: 35
“MY CHILD IS ALWAYS SICK”4 year old boy who developed pneumococcal pneumonia and bacteremia at 8 months later on developing E. coli UTI at 10 months and non typeable H. influenzae bacteremia at 2 years of age. Had been having recurrent pneumonia and sinusitis that mom thinks he cannot get over it.”. PE unremarkable.
LaboratoriesInitial immunoglobulin levels: IgM: low, IgG: normal, IgE: normal
After 2 weeks: immunoglobulin levels: IgM normal, IgG: low, IgE: normal
Diptheria and Tetanus titers: non protective
CD 19 lymphocyte count: normal
Differential Diagnosis?1. Common Variable Immunoglobulin Deficiency
2. Transient Hypogammaglobulinemia
3. Agammaglobulinemia
4. Hyper IgE Syndrome
Common Variable Immunoglobulin Deficiency
Infections usually occurs after 6 months
Can affect both genders
Non protective diphteria and tetanus titers
Treatment: Immunoglobulins
“Something not right is going on”2 month old boy previously healthy developed
right leg weakness after getting oral polio vaccine.
His dad is concern that “ something not right is going on”.
PE: right lower extremity weakness.
LaboratoriesInitial : IgM, IgG, IgA non detectable
Repeat: immunoglobulin levels non detectable
CD 19 lymphocyte count : zero
Differential Diagnosis
1. Agammaglobulinemia2. Transient hypogammaglobulinemia3. Hyper IgE syndrome4. Chronic granulomatous disease
Agammaglobulinemia
May be autosomal recessive or X-linkedAll immunoglobulins and CD 19
lymphocytes are non detectable.
“We belong to a family with immunoglobulin deficiencies”
9 month old girl who had 2 episodes of otitis media
within 3 months. No other infections. PE in
unremarkable. Two family members with CVID.
Differential Diagnosis1. Agammaglobulinemia
2. Transient hypogammaglobulinemia
3. Hyper IgE syndrome
4. Chronic granulomatous disease
Transient Hypogammaglobulinemia of Infancy (THI)
Low immunoglobulin levels that resolves between 2-3 years old.
Normal diphteria and tetanus titers
Normal CD 19 lymphocyte counts
“Rashes, asthma & infections not going away”
15-year-male presented with recurrent pneumonia and sinusitis.
Pneumatocele was observed in the chest Xray. Had several
episodes of sinusitis and pneumonia in the past. Had been
having moderate to severe asthma. PE findings pertinent for
eczema and crackles.
Differential Diagnosis1. Agammaglobulinemia
2. Transient hypogammaglobulinemia
3. Hyper IgE syndrome
4. Chronic granulomatous disease
Hyper IgE SyndromeAlso known as Job syndrome
Eczema, asthma, recurrent sinusitis, lymphadenitis
Markedly elevated IgE level
Elevated eosinophils
“Unusual germ from a facial wound”3 year girl who developed cervical adenitis that did
not improved with amoxicillin-clavulanate. The cervical
adenitis recurred and was treated with trimethoprim-
sulfamethoxazole with improvement.
Laboratories:Wound culture: Burkholderia cepacia
Immunoglobulin levels: normal
Neutrophil oxidative burst test: positive
Differential Diagnosis1. Agammaglobulinemia
2. Transient hypogammaglobulinemia
3. Hyper IgE syndrome
4. Chronic granulomatous disease
Chronic Granulomatous DiseaseCan be autosomal recessive or x-linked
Rx: Trimethoprim-sulfamethoxazole, itraconazole
Gamma interferon
“My niece always have these skin bumps”
11 year old girl who lives with her aunt had been
having repeated skin infections for 2 years. Had
been on multiple antibiotics. Pertinent PE findings generalized
impetigo and oral thrush.
IMMUNOGLOBULIN DEFICIENCY SYNDROMES IN OUR AREA
1. Hypogammaglobulinemia- X-linked, autosomal recessive
2. Common Variable Immunoglobulin Deficiency
3. Transient Hypogammaglobulinemia of Infancy
4. Hyper IgE Syndrome/Job syndrome
Pathogens Commonly Affecting Patients with CVID and Agammaglobulinemia
1.Encapsulated bacteria: Pneumococcus, E.coli, H. influenzae, Salmonella, Mycoplasma
2. Viruses: enteroviruses, hepatitis C, CMV, VZV
3. Parasite: Giardia
Pathogens Commonly Affecting Patients with CGD
Bacteria: S. aureus, Serratia marcescens, B. cepacia, Nocardia.
Fungi: Aspergillus
Pathogens & Associated Conditions
E. coli sepsis: Galactosemia
Recurrent Neisseria infection: Terminal Complement Deficiency
Deep Candida Infection: Myeloperoxidase Deficiency
Disseminated Maycobacterial Infection: T lymphocyte Deficiency
P. jerovecii infection: T lymphocyte deficiency
Encapsulated bacterial infection: Splenic Dysfuntion
10 warning signs of Immune Deficiency Eight or more new ear infections within one year.
Two or more serious sinus infections within 1 year.
Two or more months on antibiotics with little effect.
Two or more pneumonias within 1 year.
Failure of an infant to gain weight or grow normally.
10 warning signs of Immune Deficiency Recurrent, deep skin or organ abscesses.
Persistent thrush in mouth or elsewhere on skin, after 1 year.
Need for intravenous antibiotics to clear infections.
Two or more deep-seated infections such as sepsis, meningitis or cellulitis.
A family history of primary immune deficiency.
Review QuestionA 4-year-old boy was diagnosed to have chronicgranulomatous disease which of the following may be used as prophylactic antibiotic treatment?A. ampicillinB. cephalexinC. trimethoprim-sulfamethoxazoleD. ceftriaxoneE. ertapenem
Review QuestionOn a 6-year-old boy with recurrent meningococcalinfection which of the following immune deficiency syndrome will you suspect?A. common variable immunoglobulin deficiencyB. complement deficiencyC. galactosemiaD. Job syndromeE. Bruton’s agammaglobulinemia
